然后如何解决呢
后来有点怀疑 hadoop core-site.xml配置格式问题,然后让同事帮我跟进hadoop 源码,可以肯定不是hadoop问题
然后 我就想了想,之前也遇到类似的问题,我是这样配置spark-env.sh
export SPARK_LIBRARY_PATH=$SPARK_LIBRARY_PATH:/home/stark_summer/opt/hadoop/hadoop-2.3.0-cdh6.1.0/lib/native/Linux-amd64-64/*:/home/stark_summer/opt/hadoop/hadoop-2.3.0-cdh6.1.0/share/hadoop/common/hadoop-lzo-0.4.15-cdh6.1.0.jar:/home/stark_summer/opt/spark/spark-1.3.1-bin-hadoop2.3/lib/*
export SPARK_CLASSPATH=$SPARK_CLASSPATH:/home/stark_summer/opt/hadoop/hadoop-2.3.0-cdh6.1.0/share/hadoop/common/hadoop-lzo-0.4.15-cdh6.1.0.jar:/home/stark_summer/opt/spark/spark-1.3.1-bin-hadoop2.3/lib/*12
这个配置是之前fix这个问题的,但是 是很久之前的事情,我早已经忘了,所以这是平日写博客的好处,把每次遇到的问题全部记录下来
恩?如果我指定具体.jar包,那就没问题了,但是在spark中 难道必须要用 * 来指定某个目录下的所有jar么?那这个跟hadoop还真不一样呢,在hadoop中 我们要指定某个目录下的jar包,都是/xxx/yyy/lib/
而spark必须要求/xxx/yyy/lib/*,才能加载到这个目录下的jar包,否则就会包如上错误
修改后的spark-env.sh配置文件
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/cluster/apps/hadoop/lib/nativeexport SPARK_LIBRARY_PATH=$SPARK_LIBRARY_PATH:/home/cluster/apps/hadoop/lib/nativeexport SPARK_CLASSPATH=$SPARK_CLASSPATH:/home/cluster/apps/hadoop/share/hadoop/yarn/*:/home/cluster/apps/hadoop/share/hadoop/yarn/lib/*:/home/cluster/apps/hadoop/share/hadoop/common/*:/home/cluster/apps/hadoop/share/hadoop/common/lib/*:/home/cluster/apps/hadoop/share/hadoop/hdfs/*:/home/cluster/apps/hadoop/share/hadoop/hdfs/lib/*:/home/cluster/apps/hadoop/share/hadoop/mapreduce/*:/home/cluster/apps/hadoop/share/hadoop/mapreduce/lib/*:/home/cluster/apps/hadoop/share/hadoop/tools/lib/*:/home/cluster/apps/spark/spark-1.4.1/lib/*123
当再次执行上述代码就没有问题了
但是 但是 但是
如果 我把 /home/cluster/apps/hadoop/lib/native 改成/home/cluster/apps/hadoop/lib/native/*
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/cluster/apps/hadoop/lib/native/*export SPARK_LIBRARY_PATH=$SPARK_LIBRARY_PATH:/home/cluster/apps/hadoop/lib/native/*export SPARK_CLASSPATH=$SPARK_CLASSPATH:/home/cluster/apps/hadoop/share/hadoop/yarn/*:/home/cluster/apps/hadoop/share/hadoop/yarn/lib/*:/home/cluster/apps/hadoop/share/hadoop/common/*:/home/cluster/apps/hadoop/share/hadoop/common/lib/*:/home/cluster/apps/hadoop/share/hadoop/hdfs/*:/home/cluster/apps/hadoop/share/hadoop/hdfs/lib/*:/home/cluster/apps/hadoop/share/hadoop/mapreduce/*:/home/cluster/apps/hadoop/share/hadoop/mapreduce/lib/*:/home/cluster/apps/hadoop/share/hadoop/tools/lib/*:/home/cluster/apps/spark/spark-1.4.1/lib/*123
尼玛 就会报错如下:
